Abstract
OBJECTIVES: To describe the possible relationship between the use of antipsychotic drugs and the presence of metabolic syndrome. Other objectives are to list the main side effects of antipsychotic treatment, and to determine if there is any pharmacological treatment that can contribute towards counteracting metabolic syndrome. MATERIAL AND METHOD: A narrative bibliographic review was carried out of the following databases: PubMed, Cochrane, CINAHL, IBECS, LILACS and HealthCare. Preference in the selection process was given to clinical trials and systematic review articles or review articles and some articles that were considered relevant because of their content. The time period was limited to between January 2014 and November 2019. The languages were English and Spanish. Repeated articles and those that were not related to the objectives were rejected. The search criteria were: "antipsychotic AND metabolic syndrome"; "schizophrenia AND metabolic syndrome"; "bipolar disorder AND metabolic syndrome"; "metabolic syndrome AND suicide NOT disorder"; "metabolic syndrome AND prisons"; "metabolic syndrome AND prolactin". RESULTS: 24 articles were selected out of the 510 that were consulted. The relationship between atypical antipsychotics and metabolic syndrome was evident. Other anticholinergic, antidopaminergic effects, extrapyramidal syndromes, neuroleptic malignant syndrome, hypotension, arrhythmias, sedation, hypovitaminosis D, increased prolactin, sexual dysfunction, sleep disturbances, etc. are also highlighted. Pharmacological associations with other drugs were also found. DISCUSSION: There is a relationship between the use of atypical antipsychotics and weight gain, lipid disorders, glucose and high blood pressure. There are some associated drugs that decrease some symptoms (ranitidine, topiramate, metformin, melatonin, modafinil). Patients taking this type of medication should be monitored and encouraged to lead healthy lifestyles.
